Use air as the heat transfer medium, and place a thermometer or temperature sensor in the temperature measurement. In the temperature range where the temperature enters the product action, the lower limit of the recovery temperature minus 3K to the product action, and the upper limit of the recovery temperature plus 3K, the temperature rise and fall rate should be ensured not greater than 1K/min, during which the air in the temperature measurement area must be checked Stir thoroughly to make the temperature distribution uniform: the temperature uniformity in the temperature measurement area is within 0.4K. Resistance between terminals Initial value: ?50m?; After life: ?500m?; Test load: DC 6V, 10mA. Under standard atmospheric conditions, the insulation resistance is tested with a DC500V insulation resistance meter and the rated voltage is greater than or equal to 100M?; under standard atmospheric conditions, the electrical strength is under standard atmospheric conditions.
